"Still Alive"[1] is a song featured in Portal. It is sung from the perspective of GLaDOS and used as the song that runs over the game's end credits. It was written by Jonathan Coulton and performed by Ellen McLain, the voice of GLaDOS.[2]

Screenshot of the Portal end credits, featuring the credits, the "Still Alive" lyrics and a related image, here the science symbol.

While the song is played, the lyrics are displayed on the left of the screen as a letter written by GLaDOS to Chell, with other words not featured in the song, the words being written at the same time they are sung. On the right of the screen, the game credits roll, and under it logos of words related to the song lyrics displayed in ASCII art follow each other, such as the Aperture Science logo, the Black Mesa logo, a fire or a piece of cake. The lyrics consists of "Forms" similar to the ones used for the Enrichment Center Test Subject Application Process on ApertureScience.com: the first verse is titled "FORM-29827281-12: Test Assessment Report" ("Want You Gone" from Portal 2 is "FORM-29827281-12-2"), the second verse is titled "FORM-55551-5: Personnel File Addendum", and the bridge / third verse is titled "FORM-55551-6: Personnel File Addendum Addendum". The postscripts do not belong to a form.

Although her physical form was comprehensively destroyed by Chell at the end of Portal, "Still Alive" suggests that GLaDOS is still functional, is "not even angry" at Chell for what she has done, and considers the monitoring of her performance through the Test Chambers a "huge success" for those who are "still alive". This is confirmed in Portal 2, where GLaDOS is indeed still "alive" and forces Chell to resume her tests.

The idea of having a song in Portal during the credits was inspired by God Hand, one of Erik Wolpaw's all time favorite games.[3]

Jonathan Coulton got involved with Valve after two developers approached him following a concert in Seattle. They asked him if he would like to write music for the company, and due to his fandom for the Half-Life series, he immediately accepted. After discussing what they should do, he and the developers settled on working on Portal. He stated that GLaDOS' passive-aggressive nature, which he shared, made it difficult to get her voice out of his head. When asked why more video games do not end in song, he stated that while movies are easier to convey with a story, it is more difficult to do in video games. As a result, GLaDOS singing after the player has grown accustomed to her, and appears very natural.[4]Kim Swift explained that they chose to play "Still Alive" during the ending so that players would leave the game happy.[5]

The song received significant praise for its humor and the quality of its performance. The Rice Thresher editor Joe Dwyer called the song "hilarious".[6] IGN editor Ryan Geddes called it the best game-ending song of all time.[7] Ellen McLain felt that Jonathan Coulton did a good job capturing GLaDOS with the song.[8]

In 2008, Coulton performed the song alongside Felicia Day at the Penny Arcade Expo, because he "knew it was one of those things that would just make people's heads explode". The song was also performed at the 2009 Press Start -Symphony of Games-, a yearly Japanese concert event to showcase the musical works of video games. "Still Alive" is the first Western song to be performed at the show, which included a Japanese translation by Kazushige Nojima, writer for several Final Fantasy games, and arrangement for the Tokyo Philharmonic Orchestra. Given the minimal exposure of Portal in Japan, Masahiro Sakurai, creator of Nintendo's Kirby and Super Smash Bros. series, demonstrated the game to the audience prior to the performance.[9][10]

In 2008, "Still Alive" was featured as a free downloadable song in multiple games in the Rock Band series for Xbox 360 and PlayStation 3, including Rock Band, Rock Band 2, and Rock Band Unplugged[12][13][14] to thank players for supporting the series.[15] After complaints about Rock Band Unplugged's version not being free, this was rectified and anyone who paid for it had their money refunded.[16] The Rock Band version is performed by Jonathan Coulton and three others.[17]

The following lyrics are displayed as in the Portal credits, with the same text and background colors, and a similar font. The additional, unsung quotes are brighter; the lyrics not appearing on screen are darker.

This was a triumph.
I'm making a note here:
HUGE SUCCESS.
It's hard to overstate
my satisfaction.
Aperture Science
We do what we must
because we can.
For the good of all of us.
Except the ones who are dead.

But there's no sense crying
over every mistake.
You just keep on trying
till you run out of cake.
And the Science gets done.
And you make a neat gun.
For the people who are
still alive.

Dear <<Subject Name Here>>,

I'm not even angry.
I'm being so sincere right now.
Even though you broke my heart.
And killed me.
And tore me to pieces.
And threw every piece into a fire.
As they burned it hurt because
I was so happy for you!
Now these points of data
make a beautiful line.
And we're out of beta.
We're releasing on time.
So I'm GLaD. I got burned.
Think of all the things we learned
for the people who are
still alive.

One last thing:

Go ahead and leave me.
I think I prefer to stay inside.
Maybe you'll find someone else
to help you.
Maybe Black Mesa...
THAT WAS A JOKE. HA HA. FAT CHANCE.
Anyway, this cake is great.
It's so delicious and moist.
Look at me still talking
when there's Science to do.
When I look out there,
it makes me GLaD I'm not you.
I've experiments to run.
There is research to be done.
On the people who are
still alive.
